Question 1

Which of the following is not a component of concrete?&#10;A) aggregate&#10;B) water&#10;C) magnesium&#10;D) portland cement

Accepted Answer

Magnesium is not a standard component of concrete. Concrete is typically composed of aggregate (sand, gravel, or crushed stone), water, and Portland cement as the binder. Magnesium is not used in the basic composition of concrete.

Question 2

The removal of deteriorating mortar and replacement with fresh mortar is known as:&#10;A) tech pointing.&#10;B) remortaring.&#10;C) tuck pointing.&#10;D) tuck casting.

Accepted Answer

Tuck pointing is the correct term for the process of removing deteriorated mortar from the joints of a masonry structure and replacing it with fresh mortar. This technique is often used in brickwork to improve the appearance and structural integrity of the masonry.

Question 3

EIFS is an acronym for:&#10;A) Excellent Insulating and Finishing System.&#10;B) Excavating Interior and Fluid System.&#10;C) Extensive Intubating and Finishing System.&#10;D) Exterior Insulating and Finishing System.

Accepted Answer

EIFS stands for Exterior Insulating and Finishing System, which is a type of building system that provides exterior walls with an insulated, water-resistant, finished surface in an integrated composite material system.

Question 4

The term &#34;fenestration&#34;refers to:&#10;A) windows.&#10;B) roofs.&#10;C) foundations.&#10;D) floors.

Accepted Answer

Fenestration refers to the design, construction, or presence of openings in a building, including windows, doors, vents, wall panels, skylights, curtain walls, or louvers. The term is most commonly associated with windows.

Question 5

The weight of a building's ceilings would be an example of a ________ load.&#10;A) shear&#10;B) live&#10;C) dead&#10;D) seismic

Accepted Answer

Dead load refers to the static weight of the building itself, including its structure, walls, and, in this case, ceilings.

Question 6

The purpose of a foundation is:&#10;A) the support the roofing materials.&#10;B) to distribute the weight of the building onto stable ground.&#10;C) to act as a space separator.&#10;D) All of the above

Accepted Answer

The primary purpose of a foundation is to distribute the weight of the building onto stable ground, ensuring structural stability and preventing uneven settling.

Question 7

Pilings are:&#10;A) a type of load-bearing wall.&#10;B) a component of a deep foundation.&#10;C) a type of footing.&#10;D) a component of a shallow foundation.

Accepted Answer

Pilings, also known as piles, are long, slender columns typically made from wood, steel, or concrete that are driven into the ground or drilled in place to form part of a deep foundation system. They are used to support structures by transferring their load to a deeper, more stable layer of soil or rock below the surface, which is not achievable with shallow foundations.

Question 8

Concrete is:&#10;A) porous.&#10;B) a type of artificial stone.&#10;C) a substance that cures, rather than dries.&#10;D) All of the above

Accepted Answer

Concrete is porous, allowing water and air to pass through it, which is why it can suffer from freeze-thaw cycles and needs sealing for certain applications. It is considered an artificial stone because it is manufactured through a controlled process of mixing cement (itself a manufactured product), aggregates like sand and gravel, and water. The process of concrete setting and hardening is a chemical reaction known as hydration, where the concrete cures and gains strength over time, rather than merely drying out by evaporation of water content.

Question 9

We would prefer to have insulation with a ________ and windows with a ________.&#10;A) low R-value; high U-value&#10;B) high R-value; low U-value&#10;C) low R-value; low U-value&#10;D) high R-value; high U-value

Accepted Answer

High R-value insulation is more effective at preventing heat transfer, making it preferable for energy efficiency. Windows with a low U-value have better insulation properties, reducing heat loss.

Question 10

The purpose of insulation is to:&#10;A) provide an attractive interior finish.&#10;B) provide a barrier against heat transfer.&#10;C) provide an attractive exterior finish.&#10;D) All of the above

Accepted Answer

Insulation is primarily used to provide a barrier against heat transfer, helping to keep heat in during the winter and out during the summer, thereby improving energy efficiency in buildings.

Question 11

The term &#34;low-e&#34;with respect to windows refers to:&#10;A) low energy.&#10;B) low exterior heat transfer.&#10;C) low emissivity.&#10;D) low expansion.

Accepted Answer

The answer of The term &#34;low-e&#34;with respect to windows refers...

Question 12

Using three panes of glass in a triple-glazed window:&#10;A) creates two thermal breaks&#10;B) reduces the likelihood of glass breaking&#10;C) creates three thermal breaks&#10;D) Both B and C

Accepted Answer

The answer of Using three panes of glass in a...

Question 13

One of the hazards of not installing gutters on a sloped roof is:&#10;A) water infiltrating the basement walls.&#10;B) water leaking through the shingles onto the ceiling below.&#10;C) water not draining off the roof, leading to a roof collapse.&#10;D) water seeping through the roof into the walls.

Accepted Answer

The answer of One of the hazards of not installing...

Question 14

The higher a building material's R-value, the greater the material's insulating ability.

Accepted Answer

The answer of The higher a building material's R-value, the...
